Maybe I’m in the minority, but one of the attributes I appreciate about Pi-Hole, is that is is purpose-built, without the superfluous bells-and-whistles. DNS and blacklisting is its core competency, and it does a bang-up, stable job at that.

I guess I go by the old adage “using the right tools for the job”; offloading to dedicated hardware/software (I use Pi-Hole instead of DNSBL on my dedicated firewalls).
